A short boy sits on a seat suspended by a light string from a fixed point O and starts swinging in a vertical plane from the extreme position P with a small amplitude the graph which shows the variation of the tension in the string with time 't' is:

A particle of mass m is suspended from a fixed O by a string of length L. At t = 0 , it is displaced from its equilibrium position and released. The graph which shows the variation of the tension T in the string with time t is :

A particle of mass m is suspended from a fixed point O by a string length l.At t=0, it is displaced from its equilibrium position and released.If T is the tension in the string with time t, then the correct graph is

A particle is suspended by a light vertical inelastic string of length 1 from a fixed support. At its equilbrium position it is projected horizontally with a speed sqrt(6 g l) . Find the ratio of the tension in the string in its horizontal position to that in the string when the particle is vertically above the point of support.

A small ball is suspended by a string from the ceiling of a car. As the car accelerates at a rate ‘a’ the string makes an angle '/theta' with the vertical in equilibrium. Then the tension in the string is :

A particle starts from rest at the extreme position and makes SHM with an amplitude A and angular frequency omega . Its displacement at time 't' is

A 6.0 kg object is suspended by a vertical string from the ceilling of an elevator which is acceleration upward at a rate of 2.2ms^(-2) . the tension in the string is
